4-Methylphenylacetylene

Description:

4-Methylphenylacetylene, also known as p-tolylacetylene, is an organic compound characterized by its alkyne functional group, featuring a phenyl ring substituted with a methyl group at the para position relative to the acetylene group. Its molecular formula is C10H10, and it has a linear structure due to the triple bond between the carbon atoms in the acetylene moiety. This compound is typically a colorless to pale yellow liquid with a distinct aromatic odor. It is insoluble in water but soluble in organic solvents such as ethanol and ether. 4-Methylphenylacetylene is known for its applications in organic synthesis, particularly in the formation of more complex molecules through reactions such as coupling and polymerization. Additionally, it exhibits interesting electronic properties due to the conjugation between the phenyl ring and the alkyne, making it a subject of study in materials science and organic electronics. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested.
